The latest confirmed development in the lower archive flood map is that the council records a decision for this window and gives its written reason. The update comes from the map room under Ferry House; the board outcome is that it retained the existing rule and published the reason for doing so.
Ava Korr, municipal map archivist, confirmed 58 map marks with a dated source note in the file. The previous window recorded 57; the totals do not settle whether the line records a lost spill channel or a later copyist’s change.
The unresolved point is specific: The line is visible on the surviving copy. The archive has not found a matching field survey or a named hand. The board has recorded that it retained the existing rule and published the reason for doing so.
The current action follows the board outcome that it retained the existing rule and published the reason for doing so.
NEXT UPDATE: The board recorded the outcome that it retained the existing rule and published the reason for doing so. A fresh window will use a new date and source record.
